current
Used to set the rated motor current
for motor overload detection (OL1)
based on the rated motor current.
Note Motor overload detection
(OL1) is disabled by setting
the parameter to 0.0.
Note The rated motor current is
default to the standard rated
current of the maximum appli-
cable motor.

teristics
Used to set the motor overload
detection (OL1) for the electronic
thermal characteristics of the motor.
0: Protection characteristics for gen-
eral-purpose induction motors
1: Protection characteristics for in-
verter-dedicated motors
2: No protection
Note If a single Inverter is con-
nected to more than one mo-
tor, set the parameter to 2 for
no protection. The parameter
is also disabled by setting n32
for rated motor to 0.0.
